Volume Master автор Elesari Labs

Volume Master is an elegant, lightweight audio booster that lets you amplify the sound of any website far beyond what your browser and operating system allow on their own. Whether you're watching a quiet interview on YouTube, a lecture recorded at low volume, or a video call where someone's microphone is too soft, Volume Master pushes audio up to five times the original level — instantly, without downloads, plugins, or system changes.

What it does
Volume Master intercepts the audio of <audio> and <video> elements on the page using the Web Audio API's GainNode and multiplies the signal by up to 5×. It works on virtually every site with embedded media — YouTube, Vimeo, Twitch, Spotify Web, SoundCloud, Netflix, news sites, podcast players, and anywhere else browser audio plays.

Features
- 0% to 500% range — a precision slider lets you dial in exactly the level you want, from complete mute to five times the original loudness
- Live feedback — audio adjusts in real time as you drag the slider; no release-and-wait
- Manual entry — type any exact percentage when the slider isn't precise enough
- Six presets — one-click access to 0%, 50%, 100%, 150%, 200%, and 300%
- One-tap reset — return to 100% (default) instantly
- Per-browser or per-tab mode — by default, one volume applies everywhere; flip the toggle to give each tab its own independent volume
- Persistent across navigation — your boost setting stays applied when you click links within the same tab
- Light & dark themes — light by default, with a one-click theme toggle; your choice is remembered
- Clean, modern design — Inter typography, animated gradient accent when active, thoughtful motion with reduced-motion support
- No ads, no tracking, no accounts — purely local, purely functional
